Consolidated Electronic Wire & Cable is a leading provider of various cable solutions. With a century of experience, we are proud to offer various types of high-performance coax cables that deliver optimal efficiency and reliability across a range of applications. As part of our product offerings, we can provide LMR® type of cables in different configurations to suit your needs.
What is LMR Cable?
Low loss coaxial cables, or coax cables, are used in various transmission applications such as Wi-Fi, cable television, digital audio, radio frequency networks, cellular networks, Wireless Local Area Networks (WLAN), and several other systems that need low signal attenuation. Most coax cables fall into one of two categories, RG (Radio Guide) and LMR, but unlike most coaxial cables, LMR cables use tinned copper and aluminum tape for their shielding rather than bare copper, tinned copper, or aluminum tape alone. This results in better shielding effectiveness.
LMR is newer and better than RG cable, originally designed to replace certain RG cables. LMR cables are rated for a 6 GHz maximum operating frequency and can hold up in environments with temperatures up to 85° C. These cables are typically marked “LMR-#,” with the number indicating the approximate cable diameter. For example, LMR-400 has a 0.405″ OD (outer diameter).
Types of LMR Cable
There are several types of LMR cables, including:
- LMR-100A (CEWC-100). The LMR-100 coaxial cable is designed to replace RG-316 and RG-174. It’s very thin and has more than double the shielding of RG-174, which significantly cuts down on signal interference.
- LMR-195 (CEWC-195/CEWC-195UF). This coaxial cable was made to replace RG58 and RG142. It has superior shielding and 20-33% less attenuation.
- LMR-200 (CEWC-200UF). The LMR-200 has the same 0.195″ OD as the LMR-195 cable but a slightly larger center conductor allowing for less signal loss than the LMR-195.
- LMR-240 (CEWC-240/CEWC-240UF). This was designed to replace the RG8X cable. LMR-240 cable has a 35%-64% less signal loss than RG8X.
- LMR-400 (CEWC-400/CEWC-400UF). Made to replace RG8, the LMR-400 cable is the most common LMR cable. It has another variation known as LMR-400-75, one of the few LMR cables designed for 75 ohm applications.
- LMR-600. Unlike other LMR cables, LMR-600 wasn’t made to act as a replacement for RG coax cables. It has a thick and powerful build, with the capability of transmitting signals up to 500 feet. This makes it ideal for application in powerful satellite frequency transmissions.
LMR coaxial cable can be used virtually anywhere high-performance coaxial cables are used. For example, they are ideal for:
- Drop-in Replacement for some RG Cables
- Short Antenna Feeder Runs
- Jumper Assemblies in Wireless Communications Systems
- Applications that require an easily routed, low loss RF cable, such as GPS, WLAN, GPS, Mobile Antennas, and More
